I wonder whether this bug is actually in compiz and not in gnome-screensaver. There are some known problems with non-trivial X config in gnome-screensaver, for instance randr-1.2 dual-head [1], which lead to the unlock window not being displayed at all (but entering the passwd unlocks and restores the display fine). Conditions are different here, but the result looks similar.
Did any of you guys reproduce with another screensaver instead of gnome-screensaver? Brice [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=420339 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
